R&I continues to confuse climbers by calling the knot in question a "variation" of the EDK (or more accurately the flat-overhand, or flat overhand bend if you want to be technical).
They did the same with this poorly researched article pack in March:
My comment then:
...EDK is not "a version of the flat-8". Your readers deserve more accurate reporting. You should clearly show the EDK (more accuratly called the flat over-hand), the eight-in-line (safe but hard to untie) and the flat 8 (deadly and easily capsizes). The mis-understanding between these three very different knots (not versions) has caused enough confusion and accidents for decades.
A reverse traced 8 bend is 100% safe and lays very "flat", so I can see why so many new climbers confuse that bend with tying an 8 via the same method one ties a flat-overhand, except it's one more wrap around both strands before pulling through the formed loop. This way of tying a "flat eight" as media likes to call it has been known to capsize and fail under body-weight for decades, yet the existence of the reverse traced 8 with looks almost identical, continues to deceive newish climbers and unfortunately keeps leading to loss of life.
You probably don't realize it, but in your fervor to post your perceived expertise and store bought credentials, that you misquoted the original article?
"and tied the ends together with a flat figure-8 knot, a variation of the Euro Death Knot (EDK)."
Your opinion loses all credibility if you can't even read correctly. Tool.
